The song was a commercial success, reaching the top of the charts in Australia, Belgium, Ireland, Italy, Japan, Netherlands, New Zealand, Spain and the United Kingdom, where it was Madonna's first number-one single. In the United States, the song was only available as the B-side of the 12-inch single of "Angel", therefore it was ineligible to chart on the Billboard Hot 100 according to the rules of the time. By the end of the 1980s, "Into the Groove" was honored by Billboard magazine as the Dance Single of the Decade.
Madonna's inspiration behind the song was the dancefloor, and she wrote it while watching a handsome Puerto Rican man, across her balcony. Initially written for her friend Mark Kamins, Madonna later decided to use it as the soundtrack of her film Desperately Seeking Susan. "Into the Groove" was recorded at Sigma Sound Studios. A remixed version, titled "Into the Hollywood Groove", was created by Madonna in 2003 for a Gap commercial and featured a rap by Missy Elliott. A promotional CD single was given free with any purchase of jeans instore.
I can't help but dance and sing whenever I hear this song.
